The Lowdown
Hey, Rusty here again. Let’s talk feet and miles per hour for this Karramarro outlook. It’s been a lean stretch, and I’m not gonna sugarcoat it – most of the next sixteen days are a bust. The first real chance to get wet doesn’t come around until Tuesday, the 25th of August.
From now until the 21st, it’s a wasteland. Tiny dribbles of swell, nothing over 2 feet, and the conditions are just sad. The 17th morning has a 4ft NW swell going glassy, but with a 7-second period, it’s not gonna wrap around that point properly. The 22nd morning shows a 4ft NW swell with clean cross-off wind, and the energy is moderate (309), but it’s a long shot. The 23rd morning is similar, with 4ft and clean, but again, it’s a week out.
The one that’s got my attention, the clear standout, is the Tuesday afternoon, the 25th of August. That afternoon, we’ve got a 7ft WNW swell rolling in. That’s a heavy wave – too big for learners, but for the advanced crew this spot is built for, it’s a proper session. The wind is glassy, and the combined energy is strong (475). The period is only 7 seconds, so it’s not going to be that long, peeling point break dream, but with that much water moving and clean conditions, it’s going to be a ripper. Mark that afternoon.
The 23rd morning is a decent backup, with 4ft NW swell, clean cross-off wind, and moderate energy (352). It’s a good option, but the 25th is the one.
Water temp is worth noting – on the 11th, it’s 75°F, which is 4°F warmer than normal. That’s a noticeable difference, so you’ll be comfortable in a spring suit.
So, the call is for the Tuesday afternoon, 25th of August, with 7ft WNW swell, glassy conditions, and strong energy. That’s the standout. The 23rd morning is your next best bet. The rest is a whole lot of waiting.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
